Our Purpose

511 Contra Costa is a comprehensive Transportation Demand Management (TDM) program that promotes alternatives to the single occupant vehicle. We encourage the utilization of shared modes of transportation, bicycling and walking that results in a reduction in single-occupant vehicle trips. We can all reduce traffic congestion and improve air quality by maximizing the use of our entire transportation network. Commute options include ridesharing (carpool, vanpool, transit, train), telecommuting, biking and walking.
